備注：
本頂針使用SKF-LGMT2專用潤(rùn)滑油，請(qǐng)勿使用其他不同成分之潤(rùn)滑油。
產(chǎn)品型號(hào)中有“A"的表示頂針有附螺帽
徑向力數(shù)據(jù)參考：加工件重量+車削力量
配件中的頂針子，型號(hào)有“A"的為加長(zhǎng)型頂針子。
軸向力據(jù)參考：尾座油壓壓力數(shù)據(jù)
非標(biāo)需求可定制
保留技術(shù)更改的權(quán)利
Remarks
1,For the lubricating oil,SKF-LGMT2 is designated,others aren't allowed
2,if "A" is behind the center model name,it denotes a draw-off nut attached.
3,About radial force data, please refer to workpiece weight and machining force.
4,if "A" is behind the center interchangeable tip name,it denotes the tip is extended length.
5,About axial force data, please refer to the hydraulic pressure data of the tailstock.
6,For live centers, SKF lubricating oil is designated, it is waterproof.
7,Customized order can be accepted.
8,Subject to technical changes.
